How i can fix this compatibilty issue for pre lollipo as well as other devices.@Ekalips — Pranesh Sahu, Jun 29 '17 at 10:16
First thing: Why is your `android:startColor` and `android:endColor` referencing same attr? If you want only one color - use `` tag. Second thing: Try to replace all `?attr/` with `@color/...` — Ekalips, Jun 29 '17 at 10:19
I got the same issue. if that custom_button_selected.xml file is located in drawable-v21 folder,copy the same file to drawable folder also. — Kakumanu siva krishna, Jun 29 '17 at 10:57

StateListDrawable can be used to change state of an button (pressed, focused...) and if you are going to use your custom_button_selected.xml as background to change states of your buttton then you are missing drawable inside your selector particulary inside your item tag as it is required. Something like this:

<item android:state_pressed="true" android:drawable="@color/transparent_color8"> .... </item> - or whatever color you wanna use
